*The Book of Kohelet, or Ecclesiastes, is read during Sukkot. This book includes the “time for every purpose under heaven” verses (3:1-8) which Pete Seeger used for “Turn, Turn, Turn.”

The words of Kohelet son of David, king in Jerusalem.
Utter futility! –said Koheleth —
Utter futility! All is futile! [havel havalim ha-kol havel]
What real value is there for a man
In all the gains he makes beneath the sun? (1:1-3, Jewish Publication Society translation)
